Homeless man becomes a social-media crusader

A homeless man in Washington, D.C., has become a force to be reckoned with in city politics, thanks to his 4,500-plus Facebook fans and 800 Twitter followers. Eric Sheptock logs on for free at an area nonprofit, and uses his social-media following to draw attention to the plight of the city's homeless -- and the government's failure to help them. "What he's been great at is surfacing information. We have mechanisms in place to respond when there are problems, but oftentimes we don't know that those problems exist," says Scott McNeilly of the Washington Legal Clinic for the Homeless.
